Definitions
- the present invention relates to a side channel compressor including an impeller housing on which are mounted at least two connecting units.
- Each of the connecting units have at least one inlet and at least one outlet orifice.
- a compressor is disclosed in German Patent No. C 43 41 266.
- each of the connecting units has one inlet orifice or one outlet orifice. Consequently, pipelines connected to the side channel compressor can only lead to the compressor housing from one direction. Thus, routing of pipelines is restricted when using the compressor, or the direction for connecting the pipelines must already be known or stipulated at the time of manufacturing or purchase of a compressor.
- the object of the present invention is to provide a side channel compressor which makes it possible to connect the necessary pipelines in different directions.
- the object of the present invention is solved by providing each connecting unit with at least one inlet orifice and at least one outlet orifice on each of the two axially opposite sides of the compressor. This arrangement enables a connection to be made in one or the other axial directions.
- Multi-stage compressors can be formed with the present invention by arranging individual housings side by side.
- connecting units extend axially at least into the parting plane of the impeller housing, then it is possible to have a direct connection of the corresponding inlet or outlet orifices of the individual compressors, since the orifices fit directly on one another in the axial direction and, consequently, no pipe parts are required as intermediate connections.
- connecting units it is also advantageous for the connecting units to be combined into a single connecting block. This results in a greater mechanical strength of the compressor.
- At least one sealing surface that is adapted in its shape and size to the shape and size of the inlet or outlet orifice is arranged on the impeller housing at an angular distance from the inlet or outlet orifice that corresponds to the angular distance existing between the inlet and the outlet orifices.
- the impeller housings of the individual compressors can be angularly displaced relative to one another by a multiple of one angular distance.
- the impeller housing can be turned into a position corresponding to the direction of the pipelines to be connected.
- FIG. 1 shows a side channel compressor having pipe connectors pointing in the same direction
- FIG. 2 shows a side channel compressor having pipe connectors pointing in opposite directions
- FIG. 3 shows two side channel compressors coupled to one another and connected in series, one having a radially and one an axially directed pipe connector;
- FIG. 4 shows two side channel compressors coupled to one another and connected in series having two radially directed pipe connectors
- FIG. 5 shows two side channel compressors coupled mechanically to one another which are uncoupled in terms of flow, each having a radially and an axially directed pipe connector;
- FIG. 6 shows two side channel compressors coupled mechanically to one another which are uncoupled in terms of flow, having axially directed pipe connectors;
- FIG. 7 shows four side channel compressors coupled mechanically to one another which are uncoupled in terms of flow, having axially and radially directed pipe connectors.
- reference numeral 1 denotes a drive motor that is flange-mounted on the impeller housing of a side channel compressor 2.
- the side channel compressor 2 includes two housing halves or connecting units 3 and 4. Connecting block 5, composed of the connecting units 3 and 4, is provided on the impeller housing.
- Inlet and outlet orifices 6 and 7 can be situated in different- directions on the side channel, for example on both axial end faces and on the circumferential peripheral side. Attached to each of these orifices 6 and 7 is a tubular piece 8, which is designed, for example, as a silencer. Appropriate pipelines can then be joined to the tubular pieces 8.
- inlet and outlet orifices 6 and 7 situated in different directions on the housing halves 3 and 4.
- the most favorably situated inlet or outlet orifice 6 or 7 can be selected for connecting the pipeline.
- the orifices 6 and 7 that are not required are each sealed by a cover 9.
- Uniformly distributed sealing surfaces 10 are premolded on the end faces of the housing halves 3 and 4, over their entire axial periphery.
- the angular distances 11 between these sealing surfaces 10 correspond both among themselves as well as with respect to the inlet or outlet orifice 6 or 7 to the angular distance between the two orifices 6 and 7.
- the sealing surfaces 10 correspond to the shape and size of the inlet and outlet orifices 6 and 7.
- FIGS. 3 and 4 each show two side channel compressors 12 and 14 which are connected in series, in terms of fluid flow.
- the fluid to be compressed is supplied via a tubular piece 8 to the inlet orifice 6 of the first side channel compressor 12 situated on the circumferential periphery of the impeller housing.
- the other inlet orifice 6 situated on the outer front end 13 of the impeller housing is sealed by a cover 9.
- the impeller housing of the second side channel compressor 14 is angularly displaced relative to the impeller housing of the first side channel compressor 12 by an angle corresponding to the angular distance between the inlet and outlet orifice 6 and 7.
- the inlet orifice 6 of this second side channel compressor 14 situated on the corresponding front end comes into engagement with the outlet orifice 7 situated on the inner front end of the impeller housing of the first side channel compressor 12.
- the inlet orifice 6 situated on the inner front end of the first side channel compressor 12 is sealed by a corresponding sealing surface 10 of the impeller housing of the second side channel compressor 14, and the outlet orifice situated on the end face of the second side channel compressor 14 facing the first side channel compressor 12 is sealed by a corresponding sealing surface 10 of the impeller housing of the first side channel compressor 12.
- the direct coupling of the corresponding inlet and outlet orifices 6 and 7 of the two impeller housings to one another is rendered possible because the connecting block 5 of each impeller housing extends axially at least into the two parting planes of the impeller housing.
- the connecting blocks 5 of two impeller housings come directly into contact, so that the orifices 6 and 7 can be directly connected, with the interposition of a sealing element.
- the sealing surfaces 10 provided on the impeller housing likewise extend right into the side plane of the impeller housing, so that they align with the contact surfaces of the connecting blocks 5 situated on the front end of the impeller housing and, thus, when two impeller housings are joined, are likewise capable of directly sealing off the corresponding orifices 6 or 7.
- FIGS. 3 and 4 are distinguished from one another merely by a different connecting position of the tubular pieces 8 joined to the outlet orifice 7 of the second side channel compressor 14.
- the tubular piece 8 joined to the inlet orifice 6 can also be attached to the inlet orifice 6 of the first side channel compressor 12 situated in the axial direction.
- FIGS. 5 through 7 show connection alternatives for operation of a plurality of side channel compressor 12 and 14 where flow in a compressor 12 is not coupled to the other compressors 14.
- the corresponding inlet and outlet orifices 6 and 7 of the individual side channel compressors 12 and 14, are covered depending on the required connecting direction of the pipelines to be connected to the side channel compressor 12 or 14.
- both series connection of certain compressors can be provided, as well as independent or parallel operation of the remaining compressors.
- the inlet and outlet orifices 6 and 7 provided on the periphery of the impeller housing render possible operation of the individual compressors that is independent in terms of flow in the case of aggregates comprised of more than two side channel compressors. This is due to the fact that the inlet and outlet orifices are accessible independently of one another.
